摘要:
采用焊接热模拟技术测定出首钢研发的X70管线钢焊接连续冷却转变曲线(SH-CCT),获得了X70管线钢焊接粗晶热影响区组织变化规律,组织性能分析表明,首钢生产的X70管线钢淬硬倾向和冷裂纹敏感性较低。
Abstract:
Adopting welding thermal simulation technology,welding continuous cooling transition curve of high Nb X70 pipeline steel developed by Shougang Group was determined,and the microstructure variation rule of coarse grain heat affected zone of X70 pipeline steel was obtained.The results of property analysis indicated that hardenability trend and cold cracking sensitivity of high Nb X70 pipeline steel produced by Shougang Group are low.
